Impact of intraoperative remifentanil on postoperative pain and opioid use in thyroid surgery

Abstract: Background and Objectives Remifentanil infusion is used as an intraoperative anesthetic for thyroidectomy, but has been associated with acute opioid tolerance and hyperalgesia. A national shortage of remifentanil provided an opportunity to study postoperative pain in patients undergoing thyroidectomy. Methods Retrospective review of prospectively collected data from an outpatient surgery center. Primary analysis compared patients treated before and after remifentanil shortage. Results Median postoperative opio… Show more

“…There were 24 studies identified, including 6 RCTs, 13 prospective observational studies, and 5 retrospective observational studies, that described mean or median consumption with either the standard deviation or the 75th percentile. 147,152,153,164-185 Opioid consumption was initially converted into morphine milligram equivalent (MME) units 186 ( Table 15 ), and individual procedures were compared. MME is a value assigned to compare the opioid dosage equivalency to another opioid.…”

“…With the patient in the prone position with just a nasal cannula for continuous oxygen supply, the patient should not receive an intravenous dose of propofol higher than the recommended 1mg/kg IV. The continuous infusion was established at about 50 μg/kg/min [32]. When using the target-controlled infusion (TCI) technology, the aim was to maintain at 1 μg/mL concentration in the plasma, but it can vary depending on the respiratory drive.…”

“…This pharmacokinetic and pharmacodynamic profile suggests that remifentanil will be useful in situations where a rapidly titratable potent opioids effect was desirable during the endoscopic spinal surgery with a predictable offset of action without prolonged respiratory depression [32]. The anesthesiologist should always keep in mind that remifentanil has a small central volume of distribution.…”

“…Remifentanil is a synthetic opioid that is commonly used during anaesthesia owing to its rapid onset, ultra-short duration of action and quick recovery ( Thompson and Rowbotham, 1996 ). Intraoperative use of remifentanil was, however, associated with paradoxically increased pain hypersensitivity, commonly known as opioid-induced hyperalgesia, and significant additional amount of opioid was required for postoperative analgesia, suggesting acute analgesic opioid tolerance ( Komatsu et al, 2007 , Guignard et al, 2000 , Crawford et al, 2006 , Suhitharan et al, 2018 , Wu et al, 2019 , de Hoogd et al, 2018 , Sanfilippo et al, 2016 , Grape et al, 2019 , Fletcher and Martinez, 2014 , Motamed et al, 2017 ). Development of acute opioid-induced receptor tolerance remains a major focus in understanding the underlying mechanism of this observation ( Guignard et al, 2000 , Vinik and Kissin, 1998 ).…”
